Craftman 4 cycle gas trimmer mo.no. 316.711970
Not much info in the question. You may have organic matter wrapped tightly between the spool housing and the shaft. To fix, removed the spool housing to acess the weed stems, grass or other stuff that could be tightly wrapped up in the shaft. If yours has the gear housing you should remove it and clean it inside as well. It will have stuff wrapped in the lower bearing so tight you may have to replace the bearing. Use wheel bearing grease when re packing gears.
SOURCE: I need to know the gas mixture ratio for a craftsman weedwacker
Hello mcguilmd:
>>All Two Stroke Engines will use a 50 to 1 Ratio using Today's Two Stroke Oils. I once had an Old Chainsaw probably from the 1950s, maybe Earlier 70s that had a sticker on it that said to use a 25 to 1 Fuel/Oil Ratio, but that would have been using Two Stroke Oils of the Time Period the Chainsaw was Manufactured. I was having a Problem with Oil Coming Out of the Muffler and Started Decreasing the Oil in the Gas. I Reduced the Oil Until it was a t a 45:1 Ratio and Decided to be Safe, I would Use a 40:1 Ratio Mix. In that Chainsaw I used 50 to 1 Ratio with no problems. Today's Two Stroke Oils compared to Yesteryears are more Efficient at Lubricating. It is like comparing Today's Synthetic Motor Oil to Motor Oils of Decades ago. All the Equipment I use in Landscaping, anything from a Weed Eater, Leaf Blower, Chainsaw, Hedge Trimmer, use 40 to 1 ratio, and I use all types of makes and models, Stihl, Homelite, Husqvarna, Shindaiwa, and Echo, Sears. I mix up a 5 Gallon Fuel can and use it in all of the Equipment for my Customers and for my Landscaping. I like my Fuel/Oil Ratio a Little Heavy, so I use a 40:1 Ratio. The Following was Copied and Pasted here from and MTD E-mail to me when I Asked for the OEMs Suggested Mixture for this Unit. The mixture, as described by the engine manufacturer, is a 50:1 ratio when using the approved types of 2-cycle engine oils.
50:1 ratio is a mix consisting of 2.5 ounces of 2-cycle oil per 1 gallon of gasoline.
The 2-cycle oil used should be approved and have one or more of the following specification titles: NMMA TC-WII, TC-W3, JASO FB, or JASO FC. NOTE: If unsure of the 2-cycle oil specifications, or the oil is not approved, use a 32:1 fuel to oil ratio. This ratio consists of 4 ounces of oil per one gallon of fuel.
NOTE: Always mix 2-cycle fuel oil and fuel in an approved gasoline safe container prior to filling the engine. Make sure to use a separate gas can for this 2-cycle fuel mixture and label it accordingly. Keep in mind that the fuel capacity of these engines normally is less than a gallon, therefore you will have to use this extra oil mixture for multiple fuel fills. Adding a fuel stabilizer will also help to increase the shelf life of fuel.
>>I Suggest Using a 40:1 Ratio and if Oil Starts Coming Out the Muffler then go to a 50:1 Ratio.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.
Good Luck

SOURCE: Have Craftsman gas weedwacker double line ran out.
take off knob that holds on the spool on bottom of weedwacker, remove spool, there are notches around the outside splines on the bottom of the spool. (the bottom is the end that fits up into the spool housing. there are 2 little holes opposite one another on the spool - one on each section. Cut two lengths of line about 6 feet long. stick line into first hole (near bottom of unit) wrap line around spool. once wrapped line gets short - to the point where you cant wrap it anymore - stick the end into one of the notches - do the same with the other line - insert spool back into housing - make sure spring is attached to the spool and lines come out of the holes in the housing - reinsert knob and tighten - make sure as you are doing this you unseat the ends of the lines off of the notches on the spool and they are out through the housing - tighten knob and you should be good to go
SOURCE: try to replace fuel line craftman weedwacker
You will need to get some TYGON fuel line. Match it up to the size of each fuel line, some of these trimmer use two different size lines, and remember which size went on which connection. You will want about a foot of each. Cut one end of each line at a 60 degree angle. With a pair of needle nose pliers, feed the angled end of the fuel line into the hole going into the tank and feed it into the tank untill you can see at the tank fill. You cut the angled end off and put your filter on the line. Pull it back until the filter lays at the bottom of the tank. Hook this line up to the supply side of carburetor. Take the other line and put it in the tank about 1" or 2"
then cut it off to fit on the carburetor. HTH
Good Day.
